Direct deposition of Sn-doped CsPbBr₃ perovskite for efficient solar cell application

Abstract

All inorganic carbon-based planar perovskites, particularly CsPbBr3, have attracted considerable attention due to their excellent stability against oxygen, moisture, and heat for photovoltaic utilization.

Numerical Analysis in DFT and SCAPS-1D on the Influence of Different Charge Transport Layers of CsPbBr3 Perovskite Solar Cells

“…As opposed to the previously reported CsPbBr 3 -based device structure, the given solar structure has higher J SC and FF values. It is seen that there are some differences between the calculated J sc and V oc values in the reported experimental results in the literature. ,,− ,− The possible reason might be that our studied ETLs and HTLs are not matched with previously studied experimental ones ,,− ,− as per their properties as well. Furthermore, optical properties also vary from absorber to absorber, which leads to solar energy absorption.…”

The effect of B-site doping in all-inorganic CsPbIxBr3−x absorbers on the performance and stability of perovskite photovoltaics

“…In a recent study reported in 2021, Abib et al designed a novel deposition strategy for the stable phase Sn-substituted CsPbBr 3 perovskite alloy with efficient and economical carbon-based all-inorganic devices with the architecture of FTO/TiO 2 /CsPb 0.998 Sn 0.002 Br 3 /carbon. 132 This newly developed strategy allows direct thermal evaporation of the synthesized pristine and metal-doped perovskite powders on various types of ETLs. Similar to previous reports, adding Sn 2+ ions into perovskite precursors decreased the density of the pinholes and enlarged the grain size of the perovskite film.…”

High‐purity synthesis of all‐inorganic CsPbBr 3 perovskite powder assisted by solubilizing organic ligand and its application to perovskite solar cells

“…Additionally, Ahmed et al used a precipitation method to apply it to PSCs capable of low temperature processes 14 and Qi et al applied powder engineering method in their study to fabricate a device with fewer defect 15 . Also, Jiang et al applied perovskite powder synthesis to the study of CsPbBr 3 ‐based solar cells 16 …”

“…15 Also, Jiang et al applied perovskite powder synthesis to the study of CsPbBr 3 -based solar cells. 16 All-inorganic perovskite is another important strategy for the commercialization of perovskite. It aims to improve the stability of perovskite by replacing thermally decomposable organic cation with stable inorganic cation in the A site.…”
